SDK: High-Performance State Channel SDK for Micro-transactions

[wagmiiii]

Repo context. accensa-app is the off-chain half of Accensa — the merchant back-office for x402 sellers on Stellar. Three workspace packages matter: apps/web (Next.js dashboard and the indexer at src/app/api/sync), packages/sdk (@accensa/sdk), and apps/demo-merchant. The Soroban contracts live in accensa-contracts.

🟢 Unblocked. Off-chain SDK feature independent of on-chain deployment.

Problem

On-chain transaction fees and latency make micro-transactions (e.g., pay-per-article) unviable. The SDK requires a complex state channel implementation to batch transactions off-chain before final settlement.

What to build

Develop a state channel protocol within @accensa/sdk. Implement logic for opening, funding, updating (via mutual off-chain signatures), and disputing/closing channels on the Soroban network.

Acceptance criteria

• Off-chain state channel update logic implemented.
• Multi-signature validation integrated.
• Dispute resolution API abstracted for merchants.
